Hi, I loved this IQ App: https://apps.garmin.com/de-DE/apps/f08d603e-14ea-444b-bb77-ec611c9d3818
Unfortunately it's not working with my 840. Does anybody know a similiar app? The comparision of the power now, during the ride, the best overall was great.
Also the developer didn't respond to my question if he could make it work with the 840 since the 1040 is actually listet as working device :(
